PASTEBOARD MAILING-*TUBE.

SPECIFICATION forming part of Letters Patent No. 363,061, dated May 1'7, 1887.

Application filed March 22, 1886. Serial No. 196,162.

To all whom it may concern: 1

Be it known that I, GERHARD E. GRIMM, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented a new and useful Improvement in Pasteboard Mailing-Tubes, of which the following is a spec fication.

My invention is an improvement on the pasteboard tube heretofore used for inclosing rolls of music, engravings, maps, &c,, for transportation through the mails, and in or der to preserve secrecy or prevent any injury to the contents it was necessary to roll the tube within an inclosing-sheet of paper of greater length to provide material to be tucked or compressed into the ends.

My invention consists of a tube formed from a strip of pasteboard, to each end of which is attached by paste or glue a rectangular piece of flexible paper, the connected ends overlap ping each other in sucha manner that said overlapping portions of the flexible end pieces are secured between the plies of pasteboard forming the tube when the blank thus prepared is rolled around the mandrel and pasted, forming a tube with extended sheet paper ends. When the desired contents areinserted within the tube, these extended portions are intended to be tucked or pressed into the ends of the pasteboard, preserving secrecy and preventing injury to said contents, thus dispensing with the use of an additional wrapper.

In the accompanying drawings, which make a part of this specification, Figure 1 is a section of the pasteboard strip A and attached overlapping end pieces, a, of which the tube is formed. Fig. 2 is a side elevation of a finished tube, B. Fig. 3 is a longitudinal section. Fig. 4 is an end view.

(No model.)

Like letters of reference in all the figures indicate the same parts.

A, Fig. 1, isastrip of pasteboard of required width to form a tube when rolled around a mandrel, its walls being connected together by pasting. To each end of this strip A is attached by glue or paste an overlapping piece, a, of flexible paper. These pieces a are rolled with the board during its formation into a tube, B, with their main portions extended parallel thereto, and are intended to be tucked into their connected ends of the pasteboard when the tube B has had the desired contents inserted within it, to preserve secrecy and prevent injury to the same.

By rolling the pieces a, with the board A, into a tube a firm and substantial connection is effected, and abundant material provided so that the overlapping portions of the end pieces are secured between the plies of the pasteboard forming the tube, substantially in the manner herein shown and described.

GERHARD E. GRIMM.
